2.2 Temperature
When used in direct sunshine or in any other hot environment the Tobii Dynavox I-Series device may have hot
surfaces. There are built-in temperature sensors that monitors the temperature. If the sensors detects tempera-
tures above the temperature specified in Table E.1 Maximum Allowed Temperature, page 55, the device will au-
tomatically trigger a Windows Shut Down or Hibernate (depending on Windows Power Button configuration) to
prevent risk of harm to the user. It may take a while before Tobii Dynavox I-Series device can be restarted, as the
unit may need time to cool down.
Do not touch the area specified in Figure E.1 Temperature Threshold Area, page 55 when the Tobii Dynavox I-
Series device is running. The specified area can reach temperatures which may cause permanent bodily harm in
the event of prolonged direct skin contact. Use appropriate precautions to avoid injury.
2.3 Power Supply and Batteries
The Tobii Dynavox I-Series device uses Lithium Ion batteries. These batteries have a storage temperature range
of between -20 ℃/-4 ℉ and 40 ℃/104 ℉ within 3 months.
If you are in a hot environment, be aware that it can affect the ability to charge the batteries. The internal temper-
ature has to be between 0 ℃/32 ℉ and 45 ℃/113 ℉ for the batteries to charge. If the internal battery temperature
raises above 45 ℃/113 ℉ the batteries will not charge at all.
Move the Tobii Dynavox I-Series device and the batteries to a cooler environment to let the batteries charge
properly.
Avoid exposing the batteries to fire or to temperatures above 50 ℃/122 ℉. These conditions may cause a battery
to malfunction, generate heat, ignite or explode. Be aware that it is possible, in a worst case scenario, for temper-
atures to reach greater than those stated above in, for example, the trunk of a car on a hot day. So, storing the
device, with batteries installed, in a hot car trunk could conceivably lead to a malfunction.
Do not disassemble or harm the battery. Pay attention to the environmental laws and regulations which apply in
your area when disposing of batteries.
For safe operation of the Tobii Dynavox I-Series device, use only chargers, batteries, and accessories approved
by Tobii Dynavox.
Do not open (except for the battery cover), or modify, the metal casing of the Tobii Dynavox I-Series device or of
the power supply, since you may be exposed to potentially hazardous electrical voltage. The device contains no
serviceable parts. If the Tobii Dynavox I-Series device or it’s accessories are mechanically damaged, do not to
use them.
If the battery is not charged or the Tobii Dynavox I-Series is not powered up by the power supply, the Tobii Dyna-
vox I-Series device will shut down.
If the Power Supply Cord becomes damaged, contact Tobii Dynavox for replacement.
Do not connect any devices with a non-medical grade power supply to any connector on the Tobii Dynavox I-Ser-
ies device.
The appliance coupler of the power supply or separable plug is used as the Mains Disconnection Device, please
do not position the Tobii Dynavox I-Series device so that it is difficult to operate the disconnection device.
Special regulations apply to shipping Lithium-ion batteries. If dropped, crushed, or short-circuited, these batteries
can release dangerous amounts of heat and may ignite, and are dangerous in fires.
Please reference IATA regulations when shipping lithium metal or lithium ion batteries or cells: http://www.iata.
